Devices mark a specific level and are generally used as a high alarm or switch. Multiple-point sensors can also be integrated in one device to add a low alarm, or to serve as a stepped version of a continuous level.

Devices are sensors or transducers. Products in this category provide outputs for processors, controllers, or data acquisition systems; however, they do not have a display or user interface. Choose this option for applications that require a switch.

Devices are simple instruments or gauges. Products provide more capabilities than sensor-only (transducer) devices, and may include a display and/or user interface. Choose this option for applications that require a simple gauge, a locally-programmable (stand-alone) unit, or a controller/totalizer.

Sensor transmitters are designed to transmit data from the sensor via a two-wire current loop. The loop has an external power supply, and the transmitter acts as a variable resistor with respect to its input signal.

User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.

Air bubblers feed a gas (usually air) at constant volumetric rate through a bubble tube submerged in a liquid. The amount of pressure needed to force the bubble from the bottom of the tube is equal to the hydrostatic pressure at that point.

Capacitive or RF admittance devices use a radio frequency (RF) technique that is based on differing dielectric constants. The impedance from the RF signals changes whenever the material approaches the sensing region.

Radar or microwave devices send a microwave pulse toward the process material. The pulse is reflected back by the material's surface and detected by the receiver. The level is inferred from the time of flight.

Radio frequency (RF) devices emit a high-frequency/low-power radio signal from a probe. When the material contacts the probe, the bridge becomes unbalanced and a comparing circuit realizes the change. This causes a relay output to change state.

Rotation paddles are small electric motors that drive a paddle which rotates freely in the absence of material. When the paddle is impeded by material, the motor senses this and typically triggers a switch.
